Denied Again by People he Hated, Calif. Gunman Improvised

Elliot Rodger pounded on the sorority house front door while, inside, the young women he yearned to slaughter were preparing for another Friday night.

The awkward 22-year-old was obsessed with exacting "retribution" for what he experienced as a lifetime of social and sexual isolation, and had planned meticulously to target as people as possible. But here again, he was denied access to those he felt should worship him.

So when no one answered after several minutes, Rodger improvised.

Walking around the corner, he found a group of students and opened fire, then took off in his black BMW through the streets of a college beach town buzzing with end-of-school year energy. Within 10 minutes, the rampage was over and Rodger was dead, apparently after shooting himself.

As authorities reconstructed the events, they would conclude that Rodger had stabbed three victims in his apartment, shot and killed three others at random, and injured 13 more either with gunshots or a car that he used as a battering ram. The mayhem unfolded within just one square mile, but included 12 crime scenes.

The killings began with the stabbings in the apartment that Rodger rented, inside a two-story courtyard building fronted by palm trees. Authorities have released few details, other than that all the victims were male and killed Friday.

Rodger then drove five blocks to the Alpha Phi sorority house near the University of California, Santa Barbara campus.

In rambling writings he titled "My Twisted World," Rodger detailed his plan to invade the sorority, which he concluded symbolized the world that tortured him - beautiful women who would have spurned him in favor of the "obnoxious slobs" whom he also despised.

"I will sneak into their house at around 9:00 p.m. on the Day of Retribution, just before all the partying starts, and slaughter every single one of them," Rodger wrote. He knew the stucco house, with its neatly trimmed lawn and hedges, well: "I've sat outside it in my car to stalk them many times."

The double front door is heavy wood, with glass etchings of the sorority's shield and an electronic keypad to get in. Several women heard Rodger's "aggressive knocking," Santa Barbara County Sheriff Bill Brown said. "Fortunately, no one opened."

Moments later came the first 911 call.

It was 9:27 p.m., and Rodger had left the door and within 20 paces encountered a group that included Veronika Weiss and Katherine Cooper. He shot and killed the two UCSB students, and wounded a third woman. All three were from the Delta Delta Delta sorority.

Two blocks and three minutes later, Rodger was at a local deli. There, he got out of his car, went inside and shot and killed Christopher Ross Michaels-Martinez. At least four other customers were inside, and surveillance video shows them scrambling for cover while a bullet hits the glass of a refrigerator door.

Sheriff's deputies responded to the scene and saw Rodger's BMW leaving, but did not know the shooter was at the wheel.

Soon after, Rodger was driving on the left side of another road so that he could be close to the sidewalk as he fired at two pedestrians. And then, more shots - this time between Rodger and the first sheriff's deputy to engage with him.

Meanwhile, Ryan Ellis was wrapping up his Friday night service at Isla Vista Church, a makeshift house of worship inside a beach home on a street filled with students - and on Friday night, parties.

A few dozen young adults were getting ready for hamburgers when shots rang out. Fireworks, someone said.

"I knew right away it was gunshots," said Ellis, who said he had been a Navy combat engineer in Afghanistan.

He ran out to the street and saw a cyclist lying on the ground, but no car around. "He was pretty messed up, lying up against a vehicle," said Ellis.

The cyclist, who was not identified, was one of two whom Rodger intentionally smashed with his car.

By now, officers were yelling at people to go inside and friends were texting friends not to go out.

After shooting at more pedestrians, Rodger encountered four sheriff's deputies running through a park. Three returned fire, and a bullet hit Rodger in his left hip, authorities said.

Speeding on, Rodger accelerated and hit another cyclist, who was thrown onto the hood with a force that crumpled the car's windshield. Soon after, Rodger careened into several parked cars. It was there, in the car, that he apparently shot himself.

"The police dragged a body out of the car," said UC Santa Barbara senior Kyley Scarlet, who was in a house next to where the car came to a halt. "It was him."
